Ozin's test determines those worthy of the two strongest Quasar units—Mercenary and Vanguard.
The test begins when all aspiring Vanguard and Mercenary students are dropped into Ozin's ground through a mass teleportation transport. Ozin's ground possesses three terrains—jungle, desert, and valley, and all three of them meet in the middle.
Each terrain contains creatures from all sides of the galaxy, ranging from friendly to dangerous. Students must survive these creatures along with the ethervores.
Scattered across Ozin's grounds are supplies and weapons that increase the length of survival for a team. The deeper into Ozin's ground, the more supplies and rewards are found; however, the stronger the ethervores encountered.
